摘要
针对布设的地铁GPS复测控制网,讨论了起算点与地铁控制网不兼容性对精度的影响和筛选方法,给出了单位权方差假设检验法的算法,实例表明该方法有效.
The influence on the precision of the metro GPS control network is discussed based on the compatibility of fixed initial points. The selecting method of fixed initial points matching the GPS network and its algorithm with the hypothesis test principle is presented. An example of repetition network is given, and the calculating results show this method is effective.
